| 摘 要： | 为了尝试利用角质颚对东海2种常见乌贼类种类进行判别,根据2015年采集的47尾虎斑乌贼和87尾神户乌贼的角质颚,采用主成分分析、逐步判别分析等方法对两种乌贼进行种类判别。结果表明,在所有12个形态参数的比较中,除了下头盖长/胴长,虎斑乌贼和神户乌贼都存在极显著差异(P0.01),虎斑乌贼和神户乌贼角质颚在雌雄群体间均不存在显著差异(P0.05)。采用逐步判别分析法对两种乌贼进行分类,虎斑乌贼判别正确率为95.7%,神户乌贼为94.3%,总判别正确率为94.8%。根据主成分分析结果,以两种乌贼主成分特征值大于1的因子中,负载值最高的形态参数比例指标构建判别函数,虎斑乌贼的判别正确率为83.0%,神户乌贼为83.9%,总判别正确率为83.6%。分雌雄对两种乌贼进行分类判别,雄性的总判别正确率为93.8%,雌性为96.6%。研究认为,乌贼类角质颚形态同样可用于种类判别。

| Abstract: | Based on 50 samples of Sepia pharaonic and 100 samples of Sepia kobiensis collected in the East China Sea in 2015, the paper studied the species identification between Sepia pharaonic and Sepia kobiensis by principal component analysis and stepwise discriminate analysis. Results showed that there were highly significant differences in the 12 morphological parameters of beak between two species except LHL/ML. There were not significant differences between male and female in both species. The total successful discrimination rate for Sepia pharaonic and Sepia kobiensis by stepwise discriminate analysis was 94.8%. The total successful discrimination rate for Sepia pharaonic and Sepia kobiensis based on the result of principal component analysis was 83.6%. The total successful discrimination rate for male Sepia pharaonic and male Sepia kobiensis was 93.8%. The total successful discrimination rate for female Sepia pharaonic and female Sepia kobiensis attained 96.6%. |
